Abstract:
In this report, we discuss the case of an multiple sclerosis (MS) patient, age 62, who learned to attain and sustain euthymia despite his ailments. He has Ehlers Danlos Syndrome (EDS), asthma, MS, urticaria, and major depression (MD). Despite thriving limitations, the patient is an accomplished scientist, who struggled for > twelve years to emerge from being confined to bed and wheel chair with MS, to walking with crutches, scuba diving, writing manuscripts, and living a positive life. Through former educators, he reacquired problem-solving habits to study the literature on his illnesses; keep records; try new therapies; and use pharmaceutical, nutritional, physical, and psychological methods to attain euthymia. With this inculcation, years later, he discovered that dimethyl fumarate (DMF) suppressed inflammation, cramping, urticaria, and asthma; and the combination of bupropion, S-adenosylmethionine (SAMe), vitamin-D3 (vit-D3), yoga, and self-hypnosis relieved MD. Then, after a 14-month respite, the patient, discovered that he had adult onset craniopharyngioma: a benign, recurring, epithelial tumor that grows from vestigial embryonic tissue (Rathke’s pouch) which formed the anterior pituitary. The tumor grows aggressively and causes surrounding tissue and function losses. It caused headaches, disorientation, bitemporal vision loss, among other problems. To emerge from this conundrum, the patient employed his relearned habits; the above antidepressant cocktail (bupropion, SAMe, and vit-D3); and with 30 fractionated stereotactic radiation treatments shrank his tumor and gained relief. This is a single case, and methods we discovered serendipitously may not work for other chronically ill patients. Consequently, we want to encourage such patients and their physicians to discuss their experiences in peer-reviewed domains so readers may acquire new perspectives that help individualize their care, and have productive contented lives.

Introduction

Treatment of major depression (MD, or major depressive disorder, MDD), concurrent with several chronic conditions, involves learning and experimentation before changes in thinking, behavior, deportment, self-discipline, medications, and nutritional supplements afford relief. MDD induces sadness, hopelessness, anger, isolation, and disables sufferers. It dysregulates sleep and hunger, destroys one’s ability to thrive, and mars joys in the lives of sufferers, caregivers, family, and friends. MDD does remit, it has no cure yet, and its toll is second only to cardiac diseases.1 Herein, we explain the case of a patient and the methods he discovered to gain and sustain euthymia. Later, the same methods helped him emerge positive from adult onset craniopharyngioma with minimum losses. We hope this report will inspire physicians and patients with chronic conditions to publish their accounts in peer reviewed journals so much insight is available to help chronically ill patients manage themselves, their diseases, and live positive productive lives.

The case

This patient has battled MDD since childhood, and it appears that most of his conditions, including MDD arise from congenital hypermobility-type Ehlers Danlos Syndrome (EDS) (Figure 1A1 and A2). EDS describes > ten connective tissue and enzyme disorders due to mutations in collagen, tenascin, and/or filamin-A gene families.35 EDS related signs seen in the patient include urticaria (Figure 1B1) and eczema (Figure 1B2); asthma; anemia; major depression (MD) indicated by ventricular enlargement,2 depression inventories,1,3,4 and occipital lobe bending (OLB)6 (Figure 1C and G); unilateral periventricular heterotopia (Figure 1D);7 multiple allergies; nasal cartilage defects4,5 (Figure 1G); infections (difficult to resolve);4,5 and multiple sclerosis (MS) related corpus callosum lesions that hamper coordination of hands, and may portend cognitive decline (Figure 1E).8,9 Figure 1 also displays MRIs of conjoined craniopharyngiomas (Figure 1E and F); and peaks representing fats and hydroxyl compounds in the MR-spectrum of the papillary cyst (MRS, Figure 1G).11 Collectively: the patient’s symptoms (headaches and hemianopsia); his MRIs; his endocrine workup; plus characteristic magnetic resonance spectroscopy MRS peaks, only seen in papillary (soft, fluid filled) craniopharyngiomas aided the tentative craniopharyngioma diagnosis without performing a surgical biopsy.1012 Craniopharyngiomas are considered benign brain tumors because their location and growth occur only in the perisellar region. However, they do recur within 3–10 years after removal through surgery and/or radiation and cause tissue and function losses when large and impinging on surrounding cerebral tissues.1012

Figure 1 Signs observed in the current case.
Notes: (A1, A2) Congenital hyper-flexibility type EDS (red arrows, elbows);4,5 (B1, B2) recurrent urticaria and eczema on torso (B1) and hands (B2);4,5 (C) MS and MDD-related ventricular enlargement and occipital lobe bending (OLB, blue and white arrows, respectively);1,2,6 OLB is also shown in (G). (D) EDS-related unilateral periventricular heterotopia (PH, red arrow), which supports the patient’s dyslexia diagnosis.7 (E) Red arrow, MS lesions along body and splenum of corpus callosum. They indicate difficulties in coordinating R/L hands and may portend cognitive decline.8,9 Yellow arrow – craniopharyngioma (0.9 cm3) comprising papillary (soft, anterior), and adamantinous (hard, posterior) cysts bound by a single epithelium.1012 (F) Yellow arrow, conjoined craniopharyngioma cysts (soft ~2.3 cm3 and hard ~0.5 cm3). At this stage, the tumor pressed against his optic chiasm (thin gray arch above the cyst, blue arrow) and caused bitemporal hemianopsia (bilateral peripheral vision losses).1012 (G) Red arrow, EDS-related nasal cartilage defect.4,5 White arrow, OLB.6 Yellow arrows, single voxel (box) MRS of papillary cyst showing characteristic alkyl fats and hydroxyl resonances at δ ≅1–2 and 3.5–4.2 ppm, respectively. Other CNS metabolites are not seen in papillary craniopharyngioma tumors. These MR-spectral characteristics are only seen in papillary craniopharyngiomas.11,12 Adamantinous cysts do not display MR-spectral resonances. Note, in this case report the corresponding author (NDS) is the patient.

Owing to recurring asthma, respiratory tract and lung infections, urticaria, and multiple allergies to fish products, Bactrim® (sulfamethoxazole/trimethoprim, morphine-based analgesics, etc.), at age 19, the patient was diagnosed selective immunoglobulin-M (IgM) deficient;13,14 and by mid-40s had lens replacements for premature cataracts; and three rhinoplasties and uvula removal to correct rhinitis and apnea. Selective IgM deficiency now appears prominently on his medical charts because when overlooked, and intravenous antibiotics not used during surgeries, he suffered infections that took months to resolve with antibiotics.

The patient belongs to a closed Indo-Iranian minority, Zoroastrians, who for centuries enforced consanguineous relations, and many families produced children with congenital maladies, viz, EDS, glucose-6-phosphate dehydrogenase and phosphoglucomutase deficiencies, multiple sclerosis, and Parkinson’s disease, to name a few.15,16 Furthermore, with regards to plausible environmental contributors to his illnesses: the patient worked for 30+ years with hazardous chemicals, and participated in scuba-diving activities involving venomous marine organisms for his research.17,18

The patient grew up in and has a stable supportive family and enjoyed a productive career with scientific publications and patents in organic chemistry, immunochemistry, and polymer science (Research Gate and Justia list 53 peer reviewed papers and 16 US patents, respectively, by this author; https://www.researchgate.net/profile/Navzer_Sachinvala2/publications and http://patents.justia.com/inventor/navzer-d-sachinvala).17,18

At 49 (January 2005), the patient was diagnosed with fulminant multiple sclerosis, which left him immobile, and unable to balance, or coordinate his hands. Three years later, he accepted disability retirement because he could not tolerate hot environments, grip and manipulate small objects, and play his piano and guitar, activities he once enjoyed. His Beck depression inventory (BDI) scores then (~30–40s), indicated severe depression (Box 1).1,6,19,20

Box 1 BDI score interpretation
Note: Data from Veauthier et al19 and Benedict et al.20

Soon after MS was diagnosed, the patient received e-mails from his former physiology and neuroscience Professor, Esmail Meisami, who was with him at the University of Tehran, 1977–1979. Meisami helped him: review physiology, neuroscience, and psychiatry concepts from current textbooks and journals; strengthen gestalt; note physical and emotional changes in him; record BDI scores (Box 1);19,20 and manage intercostal and cardiac sphincter cramps with diaphragmatic breathing.21 Like Meisami, other former teachers also suggested having consistent routines and using yoga, meditation, and self-hypnosis to manage pain, anger, and sleep.2224

Between 2005 and 2006, the patient received plasmapheresis, Novantrone® (mitoxantrone), and 6-methylprednasolone to suppress immune reactions. Then to delay relapses, he received immune modulation therapies (2007–15): Rebif® (interferon-beta-1-alpha), Tysabri® (natalizumab), Copaxone®, and Tecfedera® (dimethyl fumarate).2527

Likewise, after much experimentation with antidepressants, Bupropion,27,28 and supplements S-adenosylmethionine (SAMe),29 and vit-D3,30 were discovered; and with all his other medications (Box 2), yoga,22 self-hypnosis,23,24 and gym exercises he curbed inflammation to enable sustained euthymia.31 To date, gym exercises relieve stress, build strength, and improve stamina;31 yoga helps with balance, proprioception, and calm focus on tasks; and self-hypnosis and visualization ease pain, goal attainment, and fulfillment.2224

Box 2 The patient’s/NDS’s current medications and nutritional supplements (condition: medication, [daily dose and frequency])

Side effects of MS treatments were vertigo; cramps; sleeplessness; type-2 diabetes; weight gain (from 195 to 295 lb in ~18 months) and anger with high-dose steroid treatments; alarming elevations in serum alanine and aspartic transaminases (ALT >100, and AST >80; normal range for both ~10–40 IU/dL); NASH; seropositivity to the John Cunningham Virus (JCV, with Tysabri); vasovagal responses and anaphylaxis (with Copaxone®); and reduction in CD4+ and CD8+ T-cells (with DMF).2527,3234 Throughout, his BDI scores (20 to >40) indicated moderate to severe MD (Box 1).19,20

Remarkably, months after starting DMF in spring 2014, NDS noticed reductions in: intercostal cramps, asthma attacks, and NASH and urticaria symptoms. Side effects of DMF were fatigue, MD, and reduction in T-cell counts. By summer 2015, his CD4+ (helper) and CD8+ (suppressor) T-cell counts became unacceptable, ([normal values in parentheses] CD4+=298 [300–1,400 cells/mL]; CD8+=32 [200–900 cells/mL]; CD4+:CD8+ ratio =9.36 [0.9–3.6]), and DMF was discontinued.2527,3234

Earlier, in January 2015, upon advisement from AS (coauthor), the patient started consuming SAMe (400 mg, daily), and by late summer 2015 witnessed AST and ALT values decline from ~80 and 100 to 13 and 37 IU/dL, respectively.28,29 Furthermore, in summer that year, AS asked NDS to use vitamin-D3 (5,000 IU) to help with MDD, and it did (BDI <15 by December).20 So it appears that many changes enabled euthymia:

  • Earlier immune suppression and modulation treatments;2527
  • Curbing painful MS-related cramps, and asthma, NASH, and urticaria symptoms with DMF;32,33
  • Curbing inflammation and MDD with bupropion, SAMe, and vit-D3;29,30 and
  • Keeping consistent routines for sleep, medications, etc.2224,31

Thereafter, from late 2015 (November or December) to April 2017, the pateint enjoyed an affable and productive state of mind (BDI between 5 and 15) (Box 1).19,20 He wrote manuscripts, and enjoyed scuba-diving trips to Florida , Hawaii, and the Caribbean.

In April 2017, he complained of blurry vision, headaches, and falling. His MRIs showed extant MS lesions, and a conjoined papillary and adamantinous tumor above the pituitary (combined volume 0.5 cm3). By December 2017, the papillary and adamantinous tumors grew to 2.3 cm3, and 0.5 cm3, respectively (Figure 1E and F).10 The abutted epithelial tumors were situated anterior to the hypothalamus; pressed against his optic chiasm from below; reduced his visual acuity (RS: from 20/20 and 20/40, to 20/70 and 20/100, respectively) and caused bitemporal visual field deficits, as well as left compressive optic nerve atrophy. However, his hypothalamic, pituitary, adrenal (HPA) axis and thyroid hormones remained within normal ranges.1012

Adamantinous tumors, arise from CTNNB1 gene mutations that cause beta-catenin abnormalities as is seen in Rathke’s cleft cysts, and hard craniopharyngiomas, but not in any other tumor in the peri-pituitary region.10,12 Papillary craniopharyngiomas arise from BRAF-MAPK signaling pathway anomalies, and their single voxel proton (1H) spectra show characteristic alkyl resonances of fats (cholesterol, at δ 0.9–1.4 ppm) and hydroxyl groups (at δ 3.5–4.2 ppm). The patient’s spectra matched published spectra of papillary craniopharyngioma (Figure 1G).11 Adamantinous tumors do not show MR-spectral resonances, and in MR-images they appear as white lesions.1012

Collectively, his age, headaches, hemianopsia, all vision tests, endocrine workup results, and MRI and MRS data enabled a tentative craniopharyngioma finding without performing surgical biopsy.1012 This is because many neurosurgeons then advised the pateint not to risk surgery due to his immune, MS, and EDS issues. Consequently, his tumor was destroyed with 30 fractionated stereotactic radiation treatments (FSRT).35,36

In March 2018, the patient had R=20/25 and S=20/70 vision; his coherence tomography showed left optic nerve atrophy, blurry central vision (scotoma) in the left eye; and his tumor had reduced 82% to ~0.41 cm3.35,36 At present, he manages himself, walks a mile in ~22 minutes with crutches, runs on-spot multiple times a day with support to deal with narcolepsy, scuba-dives, and participates in writing and editing scientific review articles. His weight is 241 pounds (BMI 33.1), and weight management with episodic steroid use is a challenge.

Discussion

This patient suffers many EDS- and selective IgM deficiency-related problems, so we wanted to learn their interrelationships through the literature. We found that:

  • While many immune and EDS problems may be transmitted genetically;1,36 inheriting selective IgM deficiency is unknown.13,14
  • EDS and selective IgM deficiency are not reported to give rise to one another. However, sufferers of either ailment may have similar comorbidities: MS, allergies, susceptibility to infections, etc.13,6,13,14,31
  • Common among such patients are inflammatory mechanisms, ie:
    • Cytokines that provoke the conditions (eg, C-reactive protein, IFN-gamma, IL-1, IL-6, TNF-alpha, etc.);
    • Chemokines that attract inflammatory cells to sites of inflammation (eg, CXC, CCL2, or monocyte chemoattractant protein-1, MCP-1, etc.); and
    • Altered tryptophan metabolism, namely, over production and accumulation of kynurenic acid (KA, causes excitotoxicity); 3-hydroxylkyneurenine (3HK, free radically damages cells); and quinolinic acid (QA, causes neuron loss).

These changes are common among all inflammatory diseases: diabetes, cancer, MD, schizophrenia, etc.31 Fortunately, excess KA and metabolites are excreted from tissues, including the CNS, with physical exercises, which promote euthymia.14,31,32

Conclusion

Inflammatory maladies like MDD, MS, craniopharyngiomas, etc., are at present without cures and have huge disease burdens. Consequently, a mindset emerged in the patient to:

  • Use yoga, self-hypnosis, and visualization to stay at peace within and attain goals,2224
  • Use over-the-counter medications when pain and helplessness are overwhelming;
  • Soldier through side effects of prescribed therapies, noting effectiveness, and what stopped working after a while;
  • Keep regular schedules for routines (sleep, exercise, etc.); and
  • Tenaciously work to transcend disease-induced limitations by healthful means.

The above require rigorously studying current texts and science literature to find methods that accrue health benefits and improve mood, alertness, and physical and cognitive functioning.

We hope for all chronically ill patients, healing becomes an all-consuming puzzle to solve without giving-in to misery, or seeking untimely exit. This patient derives much joy and fulfillment by researching and finding new solutions to problems. Having said this, we realize, that methods and attitudes we discussed may not work for all patients; so, we want to read and learn new approaches to euthymia from patients and physicians who treat the chronically ill.
